TRAILER ATTACHMENT FOR TRACTORS.

.Application led November` 25, 1921, Serial No. 517,664. RenewedNovember 23, 1923.

To all whomz't may concern: n

Be it known that l, CHARLES HULL, a citizen of the United States, andresident of Tigerton, in the county of Shawano and s State of Wisconsin,have invented certain new and useful lmp-rovements ins Trailerattachments for Tractors; and Ido hereby declare that the following is afull, clear, and exact description thereof.

My invention relatesto a trailer structure and devices for connecting itto a tractor. 'Tt contemplates the Provision of a connecting meansgiving universalV movement-to a reach which extends under the frontbolster of a Wagon andris secured to the rear axle thereof. Theconnecting means is especially strong and durable and may be affixed toa standard tractor and thes structure is designed to utilize ordinarywagon parts.

Special objects of the invention are the prevention of the raising ofthe front of the tractor and the .transfer of weight of the load'fromthe trailer to the rear wheels of the tractor. This transfer givesgreater traction to the tractor, thus enabling it to pull a heavier loadand has the further advantage of utilizingthe large tires of the tractoras a support. This tends to prevent miring.

My; structure is further advantageous 1n that' it is designed to permitcloser linkage of the trailer'with the tractor which pre cludeslooseness of` operation and is especially desirable in making turns.

as the descriptionproceeds.

Reference is had to the drawing wherein, v

Figure 1 is a plan view of my device, and Figure 2 is aside elevationthereof with parts in section. l t

Supports 10 are pivotally 'mounted on tractor housing 11 by U bolts 12,the positioning ofi which prevents lateral travel of accompanying 45 thesupports with respect to the housing,

, the tapered character of the housing checking movement of the U bolts.Grooves in the housingmay be utilized for this purpose. Plates 13-13 and14- 14 connect supports 10 andare rigidly secured thereto. In practicethese -have been made of oak pieces 5 x 6, but any material may be used,

Other advantages and objects will appear" as for instance, channel iron.Plates lf-lt' are apertured to receive a kin bolt 15 passingthru a hole16 in reach 1 and secured by nut 18. Chain 19 is alixed to bolt 15 bymeans of an aperture therein, and connects Y with tractor-hitch 20.Chain 19 has such slackness as to permit vertical play of members 10 onthe housing for a limited distance, but operates to vprevent the liftingof the front of the tractor. Reach 17 is of smaller depththan supports10 and in the practical construction, it was 4, being spaced 1y fromplates 13 and 14 and resting on plates 13 and 14:. This givesa desiredamount of play to the trailer.

Wagon bolster 21 is secured by a bolt 22 to reach 17, land reach 17extends beneath the rear axle 23 and is secured thereto by U bolts24.Bolsters 21 and 25 support any desired type of wagon Structure 26. It 1sapparent that the tractor may be directed laterall with respect to' thetrailer by realson of t e ivotal connect-ion at king bolt 15.

Again, t e trailer rear axle may move up or down with respectl to thetractor, by reason of the pivotal connection on 4the housing. Thetrailer, may be of any desired length, but it will be observed that itis especiall designed to utilize standard wagon parts. he wagon partsmay be readily assembled with respect to the reach 17, and

There is no excessive or undesirab e looseness of parts and aV structureof great -is to be understood that the present invenvbolts 22- and 24may be placed in osition.

eo l

tionis not confined to such specific embodil ment, but .maybe otherwiseembodied withiu the spirit of the invention and the scope of thefollowing claims, and it will further be understood that a. substantialrange of equivalence is contemplated.

Iclaim: u

1. The combination'of a tractor axle hous- Iing, supports pivotallysecured thereto, a

two of said plates, a pin connecting said i reach with the firstmentioned pair of plates,

said reach extending between said second mentioned pair of plates andfreely slidable at all times therebetween.

2. The combination of a rear axle hous` ing, supports pivotallyconnected thereto, members connecting said supports, a reach a boltconnecting said members and sai reach, a chain connected to said bolt atits lower end, and a tractor hitch secured to said chain.

In testimony that I claim the foregoing l have hereunto set my hand atTigerton, in the county of Shawano and State of Wisconsin.

CRLES HULL.
